Motion

Define motion.

The speed $\left(v\right)$ and time $\left(t\right)$ for an object moving along straight line are related as $t^2+100=2vt$. Where $v$ must be

Is it possible that a body is at rest and at the same time is in motion?

Rest and motion are relative terms. Explain with two examples.

A particle is moving along a straight line along the positive $x$-axis such that its speed is inversely proportional to the distance from origin
[$v\propto \frac{1}{x}\Rightarrow v=\frac{k}{x}$, where $k$ is the proportionality constant].
At $t=0$, the particle is at point $A\left(x_0,0\right)$ and moving along the positive $x$-axis with speed $v_0$ $\mathrm{m} {\mathrm{s}}^{-1}$. The graph of motion of the particle for $\frac{1}{v}$ versus $x$ (distance from origin) is shown in the figure for time particle moves from point $A$ to $B$.

For an object moving along a straight line, choose the correct option

Define the term kinematics.

Which of the following is/are the example(s) of two-dimensional motion.

A car moving with a speed of $30m{s}^{-1}$takes a

U-turn in$\frac{1}{2}$  seconds, without changing its speed. What is the average acceleration during
these $\frac{1}{2}$s time?

The stopping distance of a car is $40 \mathrm{m}$ when moving with a speed of $80 \mathrm{km}/\mathrm{h}$. If the car is now moving with $40 \mathrm{km}/\mathrm{h}$, then its stopping distance will be

Differentiate between one dimensional and two dimensional motion.

Bholu and Golu are playing on a ground. They start running from the same point A in the ground and reach point B at the same time by following the paths marked 1 and 2, respectively as shown in the figure. 
  
What can we say about the distance they travelled? 

Ramesh moves from point A to B  along a straight line and then  comes back to A from B.
He keeps moving between A and B in the same manner for 10 minutes. 

Which of the following describes Ramesh’s motion?
